The app allows users to become an Epidemic Intelligence Service agent and examine a range of variables, based on factual information, in a burgeoning disease outbreak and make decisions much as a CDC decision-maker would. Should you quarantine the city? Interview people who are sick? Request more results from the lab?

According to the CDC, the app comes with three outbreak scenarios, with more coming soon. Users can post their scores on Twitter and Facebook and challenge friends to do a better job at stemming the epidemic and saving more lives.

The agency says it is using social media to educate the public about diseases and to promote an appreciation for public health work.
